Reviewer scorecard
“Deno 2's Node.js compatibility changes everything. Secure by default, great tooling, and now practical for real projects.”
“Open source with a self-hostable option. Remote config + feature flags in one tool reduces tool sprawl.”
“Deno 2 finally delivers on the promise. npm compatibility means you can actually use it without friction.”
“Solid open-source feature flag platform. The edge proxy for sub-millisecond evaluation is a nice touch.”
“Security-first runtime design is correct for the AI era where you're running untrusted code. Deno Deploy is compelling.”
“The feature flag market is crowded. Flagsmith is good but differentiation is minimal against Unleash and others.”
